Abstract
Abstract:
A CONTACT STOP FOR AN ELECTRICAL CONNECTOR
This invention provides a contact stop for an electrical connector of the type having front insertable contacts. The invention is characterized by a plate (40) of hard dielectric material located adjacent the rear face of a contact retaining insert (30). The plate (40) has a plurality of passages (41) each of which terminate at one end in a forwardly extending solid wall tubular tower (42) which has a forward end or a shoulder (43) which abuts against a rearwardly facing shoulder (23) on a contact (20) in the passage (31) of the insert (30) to limit rearward movement of the contact after it has been inserted into the insert (30).

Description
~ 5 ~ 373-~2-0~0 A CONTACT STOP FOR AN ELECT~IC~L, CONNECTOR
This invention relates to an electrical connector and more particularly to a plate in the rear of the connector that stops the rearward movement of a contact inserted from the front of the connector.
Electrical connectors generally include a plug and receptacle, each of which has an insert of dielectric material provided with multiple openings within which electrical contacts are retained. The insert is introduced into the rear end of a metal shell or housing 10 of the connector where it is held in place by some means such as a nut. Some connectors provide for rearward insertion and front or rear release of electrical contacts while other connectors provide for front insertion and front or rear release of electrical 15 contacts~ These features are desirable and faci~itate the assembly and servicing of the connector. Examples of prior art electrical connectors havin,g insertable and removable contacts may be found in U.S. patents 3,165,369 entitled "Retention System for Electrical Contacts"
issued July 12, 1966 and 3,221,292 entitled "~lectrical Connectors" issued November 30, 1965~ In the foregoing patents, the contacts are retained within the connector housing by a retention mechanism in a dielectric insert and the contacts are sealed from moisture by a separate rubber grommet which fits tightly around the incoming wires to prevent moisture ~rom entering into the area between the contacts. In the foregoing types of connector, splaying of a contact may occur when the contact is subject to forces such as during mating.
Splaying, or movement of the contact from its original axial position is undesirable because it may prevent mating with its counterpart contact in another housing.
Further, the retention mechanisms and some types of ~ 5 ~ 373-82-0480 connectors may not be strong enough to provide the additional and necessary strength to prevent further rearward movement after the contact is retained in an insert. In connectors where an additional back plate is added as a stop to prevent further movement of a contact an alignment fixture is necessary during assembly of the connector to align the passages in the back plate with the passages in the contact retaining ir,sert.
Disclosure oE the Invention This invention provides a contact stop plate for an electrical connector o the type having front insertable contacts. The invention is characteria:ed by a plate of hard dielectric material located adjacent the rear face of the insert containing the contacts. The plate has a plurality of passages each of which terminate at one end in a forwardly extending solid wall tubular tower which abuts against a rearwardly facing shoulder on a contact to limit rearward movement of the contact after insertion of the contact into the connector inser1:.
Accordingly it is an advantage of this invention to provide an improved contact stop for an electrical connector.
It is another advantage of this invention to provide a contact stop plate that does not require the use of special fixtures during assembly to align the passages in the plate with the passages in an inser~.
It is another advantage of this invention to provide a contact stop plate that provides radial support for contacts mounted in the connector insert so that the contacts do not move radially when subject to a force during mating.

FIGUR~ 2 illustrates a segment of the contact stop shown in FIGURE 1 taken along lines II-II.

Referring now to the Drawings, FIGURE 1 illustrates a plate 40 comprised of a hard dielectric material such as a 50% glass filled polyimide (nylon). The plate 40 includes a plurality of towers 41 each having a passage 42 therein that terminates in a shoulder 43 that is 15 angled inwardly towards the central axis of the passage FIGURE 2 is a cross-section of a portion of the contact stop plate ~0 that illustrates the angled shoulder 43 which is adapted to mate with a complementary 20 angled shoulder on a contact (not shown).
FIGURE 3 is a diagramatic vie~ of an electrical connector assem~ly of the type having a metal shell or housing 10; an insert of dielectric materials such as rubber 30 having a plurality of passages 31; electrical 25 contacts 20 mounted in a portion of a respective passages 31 of the insert 30; and the plate 40 ~hat stops further rearward movement of a contact 20 after it is inserted into a passage 31 from the front of the insert 30. The angled shoulders 43 in the forwardly ext.ending towers ~1 30 mate with the rearwardly facing angled shoulders 23 of respective contacts 20 to prevent rearward movement of a contact 20 once it is located and retained in the connector insert 30. The towers 41, located in respective recesses in the insert 30, provide support 35 along a portion of a contact 20, thereby providing ~ S ~ 373-82-0~80 additional radial support to help prevent a contact from moving radially from its original posi.tion during the mating of a contact with a contact in another connector housing. The angled shoulder 43 also assists in aligning the contact 20 when it is inserted into the bore 31 in the insert 30.
While a preferred embodiment of the invention has been disclosed it will be apparent to those skilled in the art that changes may be made to the invention as set forth in the appended claims and, in some instances, certain features of the invention may be used to advantage without corresponding use of other features.
Accordingly, it is intended that the illustrative and descriptive materials herein be used to limit the 15 principles of the invention and not to limit the scope thereof.
